Stefan Esser, PHP security specialist and member of the official PHP Security Response Team has, he says, had enough - in his blog he has announced his immediate resignation from the PHP Security Response Team. He states that he has various reasons for doing so, the most important of which is that his attempt to make PHP safer "from the inside" is futile. According to Esser, as soon as you try to criticise PHP security, you become persona-non-grata in the security team. In addition many of his suggestions were ignored because the developers considered Esser's choice of words, too abrasive. He says that he had stopped counting the number of times he was called a traitor when he published a bug report on a vulnerability in PHP.

Esser wants to continue to publish his reports without worrying about whether or not a patch is available. He no longer wishes to cover up the slowness of the reaction time between discovery of a vulnerability and publication of this information. It is reasonable to expect that he will be publishing substantially more vulnerabilities in PHP in the future.
